In 1925, American astronomer  by the name Edwin Hubble, provided observational evidence that all galaxies are receding away from one another, which implies that the universe is expanding. The expansion of the universe is now an established scientific fact.

This is what the Qur’an says regarding the nature of the universe:

The Arabic word musiun is correctly translated as ‘expanding it’, and it refers to the creation of the expanding vastness of the universe.

Stephen Hawking, in his book, ‘A Brief History of Time’, says, "The discovery that the universe is expanding was one of the great intellectual revolutions of the 20th century." The Qur’an mentioned the expansion  of the universe, before man even learnt to build a telescope!

 Some may say that the presence of astronomical facts in the Qur’an is not surprising since the Arabs were advanced in the field of astronomy. They are correct in acknowledging the advancement of the Arabs in the field of astronomy. However they fail to realize that the Qur’an was revealed centuries before the Arabs excelled in astronomy. Moreover many of the scientific facts mentioned above, such as the origin of the universe with a Big Bang, were not known to the Arabs even at the peak of their scientific advancement. The scientific facts mentioned in the Qur’an are therefore not due to the Arabs’ advancement in astronomy. Indeed, the reverse is true: they advanced in astronomy, because astronomy occupies a place in the Qur’an.
